Hi,

If I understand correctly the
*Cumulative Delta Bars - Trades* study uses the ACSIL sc.CumulativeDeltaTicks()
AND
*Cumulative Delta Bars - Volume* uses the sc.CumulativeDeltaVolume().

Is it possible to make available an ACSIL fonction for the
*Cumulative Delta Bars - Up/Down Tick Volume* ?

I may be wrong, but have not found it.

Probably you are looking for these functions.

sc.UpTickVolume[sc.Index];
sc.DownTickVolume[sc.Index];

@ejtrader

No. This is the up/down tick of the current bar. I want the cumulative of that.

This function seems to be available as well ( but not sure if this is what you are looking for or not)

sc.CumulativeDeltaTickVolume();

Thx @ejtrader .

sc.CumulativeDeltaTickVolume does not appear in the documentation.
And does not seem to compile.

HOWEVER ... there is an intermediate function named CumulativeDeltaTickVolume_S and a declaration of InternalCumulativeDeltaTickVolume

So.. I suppose something like this is missing in sierrachart.h ...

SCFloatArrayRef CumulativeDeltaTickVolume(SCBaseDataRef BaseDataIn, SCSubgraphRef Out, int Index, int ResetCumulativeCalculation)
{
  return InternalCumulativeDeltaTickVolume(BaseDataIn, Out.Arrays[0], Out.Arrays[1], Out.Arrays[2], Out, Index, ResetCumulativeCalculation);
}

SCFloatArrayRef CumulativeDeltaTickVolume(SCBaseDataRef BaseDataIn, SCSubgraphRef Out, int ResetCumulativeCalculation)
{
  return InternalCumulativeDeltaTickVolume(BaseDataIn, Out.Arrays[0], Out.Arrays[1], Out.Arrays[2], Out, Index, ResetCumulativeCalculation);
}

I will wait for "official" sierra reaction, but believe to be able to continue from here :)
Again, thx ejtrader.

@wwwingman - thanks. I have infact looked at CumulativeDeltaTickVolume_S and "assumed" sc.CumulativeDeltaTickVolume() this to be available similar to other functions :)

Anyway - let's see what SC team has to say on this.

Thanks

sc.CumulativeDeltaTickVolume() functions will be added in the next version.
